Synsepalum dulcificum, also known as "Miracle Fruit," makes sour foods taste sweet when consumed. An attempt was made in the 1970s to commercialise this fruit for this purpose, but it failed.

Sure, many civilizations have their own calendars that they prefer to the Western Gregorian calendar, but the majority still obey the unwritten rule of "12 months to a year." Ethiopia is not one of them. Trying to buck the trend, Ethiopians picked up on Spinal Tap's conviction that one more is always better many thousand years ago, and have been counting 13 months to their year ever since. What exactly does this imply? Well, it's still 2009 there in 2017. And so savvy tourist boards can confidently assert that the nation has "13 months of sunlight."

According to new research based on minutes of conversations between Japanese government officials in the run-up to capitulation, the Soviet Union's surprise entry into the conflict with Japan had a more crucial impact.

North Sentinel Island is home to one of the world's most isolated human populations. The Sentinelese, estimated to number around 300 people, have rejected all contact with the modern world and fired their arrows at anyone who comes within range.

The Terracotta Army was built by China's first emperor, Qin Shi Huang after he (then 13 years old) ascended to the throne in 246 BC. It was Emperor Qin's afterlife army. Objects such as statues were thought to be animate in the afterlife.

You probably don’t know this, but the calendar that we use today was invented by ancient Egyptians. Yes, ladies and gentlemen, the first calendar known to humankind was invented in Egypt. In fact, it is the year 6264 in the Egyptian calendar.

The ancient Egyptians used the 12-month calendar like we do today. However, each month was always 30 days which meant that their years were only 360 days in total causing the years to fall out of sync with the seasons. So to make up for the lost time, they held a 5-day festival at the end of each year.

Another shocking fact about Russia is that it has 12 active volcanoes! Because of its convenient position, Kamchatka is one of the most visited of these volcanoes. If you enjoy nature and stunning scenery, you should go to Kamchatka. This active volcano is home to approximately 1,000 plant species. Brown bears, lambs, and wolves also live there. You may explore Kamchatka on your own or as part of a guided excursion. If you are not fluent in Russian, an organised trip is the better alternative.

Bananas contain potassium, which decays and makes them mildly radioactive, making them one of our weirdest scientific facts. But this is one of those amusing science facts about which you need not be concerned. According to Forbes, you’d have to consume 10,000,000 bananas all at once to die of radiation exposure.

The hotel's interiors are adorned with 24-carat gold leaves that cover over 1790 square metres. The best thing is that it even has a 'Pillow Menu,' which offers guests nine different varieties of pillows! Right, I'm assuming you choose your pillow.

In the 1940s, Anne Frank was an iconic emblem of Nazi cruelty, while Martin Luther King, Jr. was the face and voice of the civil rights movement in the 1960s. The two events appear to be so far apart in history, although both people were born in 1929—on January 15, 1929, for King, and on June 12, 1929, for Frank. That's a mind-boggling truth, isn't it?

Shakespeare produced some of the world's most renowned and cherished works of literature. Yet, to build his plays and poetry, he occasionally made up his own words. In fact, Shakespeare is credited with coining over 1,700 terms, including moonbeam, hilarious, eyeball, bump, vomiting, champion, bedroom, thrill, and zany.

Japan values good manners highly, but when it comes to chowing down on bowlfuls of noodles, there’s only one way to eat: noisily. Slurping is a sign of enjoyment and also cools down the noodles as you eat. Get your chopsticks in one hand and lean over your bowl. Bibs are sometimes provided for foreigners, but by the time you leave, you should be able to polish off a bowl in a white top and walk out spotless.

Everyone knows Lake Superior is vast (it's not called one of the Great Lakes for nothing), but few people realise precisely how big it is. Lake Superior is not only the world's biggest freshwater lake, but it also carries three quadrillion gallons of water. That's enough liquid to submerge North and South America under a foot of water. It's no surprise that Lake Superior has seen so many shipwrecks.

In Japan, people don’t have signatures – they have their own seal. Known as Hanko, the seal is typically your name translated into Kanji characters, and are made from silk or plant-based paste.

They’re not necessary for tourists, but foreigners living in Japan can have one handmade in small, local shops.

Peppers are delicious, even if most people use them as a spice rather than a food. Cayenne peppers have the ability to promote blood clotting over wounds, which is a little-known fact.

Eating cayenne pepper can also help to balance blood pressure and promote internal clotting. That is, whether you eat it or apply it directly to the wound, it will help it heal faster.

Chocolate bars were not the first chocolate treat, but hot chocolate was. And that hot chocolate was nothing like we get today. It was just a bitter concoction that was often enjoyed during weddings and other occasions. Isn't this interesting?.
